Apply PuLID ✦ Flux.2 Input Parameters:

model

This parameter represents the base model on which the PuLID method will be applied. It is crucial as it serves as the foundation for the image processing task. The model should be compatible with the Flux.2 architecture to ensure optimal performance.

pulid_model

The pulid_model parameter specifies the PuLID model variant to be used. It is essential for determining the specific processing techniques and enhancements applied to the image. This parameter ensures that the correct model variant is utilized for the task at hand.

eva_clip

This parameter involves the EVA-CLIP model, which is used for extracting and integrating visual and textual features. It plays a significant role in enhancing the image by providing additional context and detail through advanced feature extraction.

face_analysis

The face_analysis parameter utilizes the InsightFace model to perform detailed facial analysis. This is particularly important for tasks that require precise facial feature recognition and enhancement, ensuring that facial details are accurately captured and processed.

image

The image parameter is the input image that will undergo processing. It is the primary subject of the node's operations, and its quality and characteristics will directly influence the final output.

weight

This parameter controls the intensity of the PuLID effect applied to the image. With a default value of 0.8, it can be adjusted between 0.0 and 1.5 to increase or decrease the effect's strength, allowing for fine-tuning based on artistic preference.

start_at

The start_at parameter defines the starting point of the effect application on the image, ranging from 0.0 to 1.0. This allows for selective application of the effect, enabling more control over the image processing.

end_at

Similar to start_at, the end_at parameter specifies the endpoint of the effect application, also ranging from 0.0 to 1.0. It works in conjunction with start_at to define the duration and extent of the effect on the image.

face_index

An optional parameter, face_index allows you to select a specific face in the image for targeted processing. With a default value of 0, it can be adjusted up to 9, providing flexibility in multi-face scenarios.

Apply PuLID ✦ Flux.2 Output Parameters:

model

The output model parameter represents the processed model after the PuLID method has been applied. It reflects the enhancements and modifications made to the original model, providing a refined version that incorporates the desired effects and improvements.

Apply PuLID ✦ Flux.2 Usage Tips:

• Adjust the weight parameter to control the intensity of the effect, starting with the default value and fine-tuning based on your artistic goals.
• Use the start_at and end_at parameters to apply the effect selectively, focusing on specific portions of the image for more targeted enhancements.

Apply PuLID ✦ Flux.2 Common Errors and Solutions:

"[PuLID-Flux2] insightface not installed."

• Explanation: This error occurs when the InsightFace library is not installed, which is necessary for facial analysis.
• Solution: Install the required library by running pip install insightface onnxruntime-gpu in your command line.

"Dimension mismatch when switching Flux2 Klein ↔ Dev"

• Explanation: This error indicates a mismatch in model dimensions when switching between different Flux.2 variants.
• Solution: Ensure that the model dimensions are compatible with the selected variant, and check for any updates or patches that address this issue.
